Abstract
The present invention relates to a kit for performing a nail correction method for a human or animal toenail or fingernail. The kit contains a composition for forming a light-curing nail brace and a primer, wherein the primer improves the adhesion of the nail brace to the nail in need of correction. The kit may moreover contain one or more spring braces to be fixed with the light-curing compositions.
Description
Kit for nail correction Field The present invention relates to a kit for per-forming a nail correction method for a human or animal toenail or fingernail. The application claims priority of the prior application DE 102017004546.1 (date of filing: 12 May 2017).
Background Various methods are known to correct toenails or fingernails. Such nails frequently have a strong cur-vature causing them to press or grow into the nail bed.
A common way of treatment is to remove the complete nail by surgery. The treatment is not only painful, but often does not result in a nail correction: The newly growing nail is frequently as curved as the original one nail was.
An alternative, non-surgical way of treatment is to fit a nail correction brace at the respective nail.
Such a brace is described in the German patent speci-fication DE 10 2005 039 147 B3. The brace engages un-der the nail, which often will lead to tissue irrita-tions. In WO 2011/039243 Al, a multi-layer polymer system is described, wherein it is intended that, by contraction and expansion of different layers in oppo-site directions, lateral tensile forces on the nail are obtained, with the consequence of a mechanical correction. As has been found, the method described in WO 2011/039243 Al is not reproducible: All efforts to reproduce such a multi-layer system, which, on the one hand, attaches on the nail and, on the other hand, de-velops the required correction forces, were not suc-cessful.

2 There is, therefore, a continuing need for means for the correction of misgrown toenails or fingernails.
Summary Surprisingly, it has been found that the kit for nail correction described in the following avoids the above drawbacks and enables in a simple way a correc-tion of ingrown fingernails or toenails. Depending on the degree of deformation of the nails (in particular on the degree of curvature), different compositions based on photopolymerizable components can be applied.
Optionally, one or more metallic spring braces can additionally be used. By the kind of attachment of the metallic spring braces, it can be excluded that mech-anical tissue irritations will occur.
Detailed Description The kit for nail correction according to the in-vention includes a) a primer, including 40-60 % of hydroxyethylene methacrylate, 40-60 % of phosphate dimethacrylate, 0.1-1.0 96 of a starter, b) at least one composition for making a light-curing nail brace, including 15-45 % of bisphenol A (di)methacrylate, urethane dimethacrylate in a proportion from 1:5 to 5:1, 85-55 % of fillers and pigments, 0.1-1 5:5- of camphorquinone, amino starter, and c) optionally one or more spring braces.

3 the investigations in connection with the present in-vention, it has been found that the adhesion of the photopolymer to the nail is critical for the success of the correction method. It turns out that the adhe-sion of the photopolymer to the nail is significantly improved when the adhesion agent described in the in-vention is employed as a primer. This adhesion agent includes 40-60 % of hydroxyethylene methacrylate and 40-60 % of phosphate dimethacrylate and 0.1-1.0 % of a polymerization starter. The polymerization starters are described below in more detail. The mixing propor-tion may vary within the percentages mentioned above.
Advantageously, the two methacrylates are included in an approximately identical proportion. It is under-stood that all components together sum up to 100 %.
The actual nail brace is formed by means of the photopolymerizable material b. This is a composition including 15-45 % of bisphenol A (di)methacrylate, urethane dimethacrylate in a proportion from 1:5 to 5:1, 85-55 % of fillers and pigments, 0.1-1 % of camphorquinone, amino starter.
The range of compositions mentioned above allows for a,different adjustment of the mechanical proper-ties, in the form of different degrees of hardness. In practice, it has proven to provide two compositions, one of which is comparatively soft, the other one be-ing comparatively hard.
The soft composition includes, for instance, 17-21 % of bisphenol A (di)methacrylate, urethane dimethacrylate in a proportion from 1:4 to 4:1, 79-83 % of fillers and pigments, 0.1-1 % of camphorquinone, amino starter.

4 The hard composition includes, for instance, 36-40 % of bisphenol A (di)methacrylate, urethane dimethacrylate in a proportion from 1:4 to 4:1, 60-64 % of fillers and pigments, 0.1-1 % of camphorquinone, amino starter.
The monomers bisphenol A (di)methacrylate and ur-ethane dimethacrylate included in the compositions are preferably included in approximately equal amounts.
Mixing proportions, wherein the two main components are included in a mass proportion between 1:5 and 5:1, are generally suitable. Particularly preferable are mixing proportions, wherein the two main components are included in a mass proportion between 1:2 and 2:1.
The material for the light-curing nail brace fur-ther includes fillers and pigments. These are sili-cate-based fillers (silica fillers), fillers based on ground barium glass (barium glass fillers) as well as polymeric particles. The particular additions have diameters in the range from 0.1-10 pm, preferably they are smaller than 5 pm. In particular, the barium glass-based fillers significantly contribute to the mechanical properties of the nail brace. In addition, pigments may further be included in the composition, in order to confer an aesthetic appearance to the formed nail brace. Further, the pigments should pref-erably have diameters in the range from 0.1-10 pm.
The compositions according to the invention fur-ther include polymerization starters that can initiate the desired polymerization reaction by irradiation with light. For this purpose, in principle, all clas-sical polymerization starters are suitable. Particu-larly suitable has proven the combination of cam-phorquinone with amino starters, namely tertiary amines (e.g., triethanolamine, N,N-dimethyl-p-tolui-=
dine, triethylamine, 4-dimethylamino bezoic acid ethyl ester, N,N-tetramethylaniline). Alternatively, for in-stance, 2-ethylanthraquinone in combination with N-phenylglycine can be used. When using such a system,

5 surprisingly, the completed composition can be stored over longer times, without a polymerization reaction taking place. Only after illumination with an adjusted light source, the polymerization reaction will occur.
For this purpose, e.g., an LED light source with a wavelength of approx. 450 nm and a light power of 1000-1500 mW/cm2 can be used.
Optionally, the kit according to the invention further includes one or more braces made of spring steel. They are made from a spring steel wire having a diameter of 0.3-1.5 mm. The brace may include one or more U-shaped loops. The metal spring brace is applied with the light-curing material described above on top of the respective nail (glued). Different from the therapy methods described above using such metal braces, it is neither required to enclose the nail at the outside, nor to provide for boreholes in the nail.
Figure 4 shows an attachment according to the inven-tion for such a metal brace.
The kit according to the invention is used as fol-lows:
First, the therapist removes the concerned nail from the nail bed. In this procedure, a strip of cloth can be inserted between nail and nail bed. Then, the nail is first treated with the primer of the kit. Care has, in particular, to be taken that the nail is dry.
The concerned nail should, in particular during the 24 hours before the application, not have been in a longer-lasting contact with water. The patient should, for instance, not have taken a bath. Short washing or showering is, however, harmless, provided that the

The concerned nail should, in particular during the 24 hours before the application, not have been in a longer-lasting contact with water. The patient should, for instance, not have taken a bath. Short washing or showering is, however, harmless, provided that the
6 nail has been carefully dried. If necessary, the nail can be dried with a hot-air blower. The primer is first applied onto the necessary locations. Normally, it is recommended to apply the primer in a sheet-like manner onto the entire nail. After application, the polymerization is started by means of a light source (preferably blue light of approx. 450 nm and 100 mW/cm2). When using a usual light source, the polyme-rization is completed after a time of 5 seconds to 60 seconds, normally 10 seconds illumination is suffi-cient.
Thereafter, the light-curing nail brace is applied.
The nail is held by the therapist by means of a tool in the desired position. The application is made in the form of lines (see Figure 1) with a line width of 2-6 mm. After the application, preferably immediately, the polymerization is started by illumination with the light source mentioned above. It is important, when doing so, to hold the nail in the desired shape. This step, too, is usually completed after a time of 5-60 seconds. Thereafter, the material can again be re-ground, so that no edges will be created, where fabric (e.g., stockings) could get caught. With strongly de-formed or very strongly thickened nails, a multitude of such line-shaped applications can be performed. If applicable, very thick nails may also be ground pre-paratorily, so that the nail is deformable again.
Grinding has, of course, to be performed before the priming process with the primer. The photopolymer may also be applied in a correspondingly thicker layer. In an extreme case, a metallic spring brace may be ap-plied. For this purpose, first, a drop of the light-curing material is applied as a point, and the spring brace is pressed into this drop (Figure 4). After light-curing of the drop, the spring brace is spanned over the nail and fixed by means of a second drop of the photopolymerizing material. The two ends of the

After light-curing of the drop, the spring brace is spanned over the nail and fixed by means of a second drop of the photopolymerizing material. The two ends of the
7 metal brace should each be visible from the inside of the drop. In this embodiment, too, a preparation of the nail using the primer is required, since otherwise the durability of the construct on the nail cannot be guaranteed.
By means of the kit according to the invention, it is also possible to enable another correction of a nail already treated with a metal brace. In particular, in the case of a tissue irritation (nail bed irrita-tion) by the classical metal brace, the classical metal brace can be removed, and the nail is then fur-ther treated with the kit according to the invention.
The compositions provided in the kit are prefera-bly supplied in correspondingly designed containers.
For the primer, in principle, vials made of glass or plastic with an application brush are suitable. The compositions for making light-curing nail braces are typically more viscous and are preferably supplied in cartridges for use together with a cartridge press or gun. All containers are preferably opaque.
With the kit according to the invention, the nec-essary materials are provided, in order to correct in-grown toenails or fingernails for humans or animals, without the drawbacks of prior art occurring. In most cases, the nail correction can be performed without the aid of metallic braces. The composition according to the invention, in particular, guarantees a clearly better adhesion to the nail than prior art composi-tions. Furthermore, the advantages of a polymer can be combined with those of a metal brace, without the drawbacks occurring that frequently appeared in prior metal braces, in particular mechanical irritations of the nail bed.

8 In an improvement of the composition according to the invention, the primer additionally includes one or more antimicotics. As has been found in practice, nails needing a correction are frequently infested by nail fungi causing additional problems. It is known that nail fungi cannot easily be treated. It turned out that the nail fungus treatment is successful, when the primer additionally includes one or more anti-micotics. The admixture is normally 0.1-2 96, prefera-bly 0.5-1 96. As an antimcotic, generally compounds are suitable that are approved for the treatment of ony-chomycoses, such as, for instance, econazole, bifona-zole, chlodrimazole, fenticonazole, ketocanazole, mi-conazole, oxiconazole, and related compounds.
In the embodiment of the invention with an addi-tion of antimycotics, the complementing addition of penetration amplifiers has proven successful. For this purpose, the usual penetration amplifiers for nail penetration can be used. Particularly successful for the present invention have proven penetration amplifi-ers based on substituted 1,3-dioxolanes, 1,5-dioxanes and acetals, in particular the substances and sub-stance mixtures marketed under the trademark SEPA .
